To all whom it may concern:

Be it known that I, WILLIAM B. OLIVER, of No. 317 Lees avenue,Collingswood, in the county of Camden and State of New Jersey, haveinvented certain new and useful Improvements in Telephone-Stands,whereof the following is a specification, reference being had to theaccompanying drawings, this being a divisional case in relation toapplication, Serial No. 321,889, sied June i5, 1906. f

My invention relates to a telephone stand, comprising a supportpivotally mounted and so balanced by means of self-contained springdevices, as` to be capable of remaining in a state of equilibrium whenplaced in any of the positions which are within the range of 4itspivotaladjustment.

Self-balancing supports of various types are now in general use ascarriers for the ordinary desk telephone stand, the support proper andthe telephone stand be- ,ing separate and distinct structures. Thisorganization, as a whole, involves the use of somewhat cumbersome parts,and one object of the present invention is Ato simplify the structure bythe elimination of certain relatively unimportant features, thusdirectly combining the transmitter casing and the receiver with theself-contained spring support, while at the same time permitting the useof the transmitter casing and re- I'ceiverin the form commerciallyemployed in the desk instruments referred to.

In the accompanying drawings, Figure I, is a view partly in sideelevation and partly in a vertical axial "section of the support and thetelephone elements combined therewith showing the foot of the support,but not the base on which said foot is preferably mounted. Fig. II, is aview in vertical axial section through the upper portion of the support,the plane of section being at right angles to that shown in Fig. I. Fig.III, is a transverse section through the support on the line III, III,in Fig. I. Fig. IV, is a front view of the upper end of the supportshowing the transmitter casing, the

main receiver hook and the auxiliary receiver' hook.

l The standard or support comprises the foot, two telescoping tubularIncmbers (which I term the upper and lower stems), and an overhangingtop portion. The

. support terminates at its lower end in a foot l0, which is adapted tobe pivotally mounted upon a suitable support. The foot l0, carries asegmental cam piece 24, stoutly supported by means of a web 25. Theupper end of the foot is cut away at each side so as to form fiatbearing faces adapted to receive the bifurcated and rearwardly curvedends 27, of the lower stem 28, which `are rotatably mounted upon thepivot 29. A stop 23,

limits the rearward movement of the standard.

The balancing devices are organized as folloWsI--The threaded tubularpiece 34. The upper end of the piece 34, is slotted and the portions 35,corresponding with the extent of the slots are turned outwardly into ahorizontal position. These portions 35, engage beneath the overhangingflange 37, formed on the upper end of the lower stem 28, so that thetubularpiece 34, is rotatably supported against upward thrust. The ringnut 32, carries a pin 38, which engages in a vertical slot 40, formed inthe lower stem 28, and preferably extending throughout substantially thegreater portion of its length. against the bearing block or shoe 42,which slides freely within the lower stem 28. Holes 43, are formedthrough said shoe 42, to permit the passage of the telephone wires whichextend down through the standard and emerge at the lower end thereof.The lower surface of the shoe 42, is adapted to ride upon the curvedsurface of the cam piece 24, when the standard is turned from a verticalposition as indicated in dotted lines.

The lower stem 28, has a relatively wide slot 45, to permit it to beturned down over the cam 24, and the configurati on of the cam surfaceis such that as the standard is turned more and more towards ahorizontal position theishoe 42, is forced upwards Within the standard,

thus compressing the spring 3l, with a progressively increasing ratio.By a proper co-relation between the strength of the spring, the curve ofthe cam, and the weights of the supported parts, substantial equilibriummay be maintained in any position of the standard, as will readily beunderstood. The upper stem 4G, also preferably tubular, is fittedtelescopically upon the lower stom, being slotted as indicated at 47,and provided with a screw clamping band 48, so that the two parts may bemaintained in any given longitudinal adjustment with relation to eachother. The upper stem 46, itself is preferably constructed in two parts,secured together at the region 50. upper stom is hollow and is adaptedto contain in its interior the circuit Wires and contact piecescharacteristic of any ordinary desk telephone instrument. Theconstruction and general organization of these Vboing well understood itis not deemed necessary to describe the same, except that so far as theyroprr'isent peculiarities dueto their present embodiment. Near the upperond of the upper stem 46, an inclined slot 5l, is formed to permit theup and down movement of the receiver hook, whose bifurcated end isindicated at 53, its shank 52, being pivotally mounted at 54, on aninclined plate 55, which affords a bearing surface parallel to the in-The lower end of the spring 31, exerts pressure The upper portion of theI clination of the slot 51. The bifurcated ond portion 53,

of the receiver hook is mounted upon the shank 52, by means of a swivelconnection 56.

The purpose oi giving an inclination to the slot 51, and pivoting theshank upon an axis inclined with relation to the axis of the standardand also oi employing a swivel mounting for the part 53, is to insurethe proper action of gravity upon the parts, irrespective of theinclination of the standard, as a whole, to the perpendicular. As beforestated, the contact pieces, et cetera, may be of any of the Well knowntypes, the spring 58, having its upper end 57, of such coniiguration asto bear laterally and upwardly against the shank 52, oi the receiverhook.

The position ofthe parts shown in the variousgures is that which occiuswhen the receiver 60, is liited from the hook, and the spring 58, hasthrown the shank 52, of the hook, to its uppermost position on the slot51. Under these circumstances, 4the spring member 58, presses the studG1, ,against the .switch 62, `and thus establishes the circuit betweensaid switch member and the line conductor 65.4 When, however, thereceiver 60, is placed upon the hook, the action of gravity causes thelatter to descend the incline of ,the slot51,

and the shank 52, of the hook forces the spring 58, in the correspondingdirection, sothat the Apressure of the stud 61, upon the switch lmember62, is relieved and the latter springs out oi contact with the member65.

It will be noted that by reason of the swive1ed connection 56, betweenthe end portion 53, and the shank 52, the receiver will hang in avertical position, no matter what may be the inclination of the standardto the vertical, and furthermore, by reason vof `the inclined axis `upon,which Athe shank 52, is pivoted, and the freedom allowed by theinclined slot, the propergravitative effect of the receiver is alwaysinsured.

The upper end 68, of the standard is reduced in size and .bent outwardlyso as to form an overhanging support for the telephone `transmittercasing 70. In the instance shown, this casing is of the ordinary typefound in desk instruments and has a rearwardly projecting part 71, whichis pivotally connected at 72, to a curved arm 73. Said arm 73,terminates in a cylindrical -boss 74, whichis pivoted upona verticalaxis by meansoi a screw pin 75, secured to a downwardly depending piece76, whichis pendulently secured to the overhanging support 68, by meansof the horizontal pivot 69. 1t

will thus be seen that the connection between the transmitter casing 70and Athesupport 68, is oi such a -character as to permit the`pendulum-wise swing ofthe casi ing, which maintains it in-its properrelation lin all the l various positions oi the support with referencevtothe vertical, and also that the transmitter casing and'mouth pieceare revoluble upon a vertical axis, thus Vgreatlyadding `to the4convenience of the device. l

An auxiliary ,receiverlhook .79, projects laterally from l the part 74,so as to both rotate and swing therewith,

cuit, although the telephone itself is temporarily not.

stasera in actual use. It will be noted that the auxiliary receiver hookisvat the right hand of the mouth piece as faced by the user, and thatit maintains its denite position with relation to the mouth pieceregardless oi' the swinging or rotating movement of the transmittercasing, thus avoiding confusion with the normal or regular receiver hookwhich is usually located at the level of the mouth piece. The circuitwires lead down Ythrough the standard and pass through the openings 43,

in the shoe 42, emerging at the foot and being then led in any suitablemanner to make connection with the induction coils,' not shown.

To avoid prolixity in my claims I-use the term selfbalancing support, asmeaning a pivotally mounted structure of the kind described, controlledbyself-contained spring devices, which together with the friction ofthemoving parts maintain the structure-and the elements carriedtherebypractically in astate oi equilibrium as against the action of gravity inany of the various-positions whichthe standard may assume.

I claim:-
